Mu makina onse amagetsi, chitetezo ndi chitetezo ziyenera kukhala patsogolo nthawi zonse. Apa ndi pomweMCCB or Chotsukira Mlandu ChowumbidwaIzi ndi zinthu zofunika kwambiri poteteza zida zamagetsi, mawaya ndi mawaya ku mafunde amphamvu komanso afupiafupi, kupewa ngozi zamagetsi ndi kuwonongeka kwa zida.
Ma MCCBndi ma circuit breaker amakono omwe amapereka ubwino wambiri poyerekeza ndi mitundu yakale komanso yakale yazosokoneza ma circuitMu blog iyi, tifufuza ubwino wogwiritsa ntchito ma MCCB mumakina amagetsi ndi momwe angathandizire kuonetsetsa kuti magetsi amagwira ntchito bwino komanso motetezeka.
1. Kutha kuswa kwakukulu
Ma MCCB ali ndi mphamvu yotha kuthyola mphamvu zambiri, zomwe ndi mphamvu yayikulu kwambiri yomwe angaithetsere bwino. Ma MCCB ali ndi mphamvu yotha kuthyola mphamvu zambiri ndipo amatha kupirira mafunde afupikitsa mpaka ma kiloampere makumi (kA). Izi zikutanthauza kuti amatha kusiyanitsa zolakwika mwachangu ndikuletsa kuwonongeka kwa mayunitsi ndi zida zomwe zili pansi pa madzi. Mphamvu yotha kuthyola mphamvu zambiri imatanthauzanso kuti ma MCCB amatha kupirira katundu wolemera, zomwe zimathandiza kuti magetsi azigwira ntchito pamlingo wapamwamba wamagetsi.
2. Malo abwino okonzekera ulendo
MCCB ili ndi makonda osinthika a ulendo omwe amalola kuti akonzedwe kuti agwirizane ndi zofunikira zinazake. Makonda awa amayambira pa mayunitsi oyendera maginito otentha mpaka mayunitsi oyendera magetsi ndipo amalola MCCB kuyankha pazochitika zosiyanasiyana monga short circuit kapena overload. Pogwiritsa ntchito MCCB, ogwiritsa ntchito amatha kusintha makonda kuti apereke mulingo woyenera wa chitetezo ndikuwonjezera magwiridwe antchito amagetsi awo.
3. Chitetezo cha maginito cha kutentha
Ma MCCB amapereka chitetezo chophatikiza kutentha ndi maginito. Zinthu zoyendera zoteteza kutentha zimayankha ku zinthu zambirimbiri, pomwe zinthu zoteteza maginito zimayankha ku zinthu zazifupi. Njira yoyendera imayankha mwachangu ndipo imagwira ntchito mwachangu kutengera momwe zinthu zilili. MCCB ikayikidwa, makina amagetsi amapindula ndi chitetezo chapamwamba ku kuwonongeka kwa kutentha ndi maginito.
4. Kapangidwe kakang'ono
Ubwino waukulu waMCCBndi kapangidwe kake kakang'ono. Amatenga malo ochepa poyerekeza ndi ma circuit breaker akale ndipo amatha kumangidwa kapena kulumikizidwa ku DIN rail, zomwe zimasunga malo ofunika kwambiri. Kapangidwe kakang'ono kameneka kamapangitsanso MCCB kukhala yopepuka, kuchepetsa ndalama zotumizira ndikupangitsa kuti ikhale yosavuta kuyisamalira ndikuyiyika.
5. Kuwongolera bwino ndi kulumikizana
Ma MCCB amakono amagwiritsa ntchito ukadaulo wapamwamba wa microprocessor, womwe umawathandiza kuti azitha kulankhulana ndi zida zina ndi machitidwe ena. Ma MCCB amawunika ndikulemba magawo monga mphamvu yamagetsi, magetsi, mphamvu, ndi kugwiritsa ntchito mphamvu, zomwe zimathandiza ogwiritsa ntchito ndi mainjiniya kuyeza thanzi lonse la machitidwe amagetsi. Kuphatikiza apo, luso lolankhulana limathandiza ma MCCB kuti azitha kulumikizana ndi machitidwe owunikira, kuwongolera ndi odziyimira pawokha, ndikukweza kasamalidwe ka makina amagetsi ndi magwiridwe antchito.
6. Yolimba komanso yodalirika
Ma MCCB apangidwa kuti azipirira malo ovuta ndipo amatha kugwira ntchito kutentha kuyambira -25°C mpaka +70°C. Amapangidwa ndi zinthu zapamwamba kwambiri zomwe sizimawonongeka ndi mankhwala ndi makina, monga polycarbonate, polyester ndi ceramic. Kuphatikiza apo, ma MCCB amakhala nthawi yayitali kwambiri, amakhala zaka 10 mpaka 20 kutengera momwe amagwiritsidwira ntchito komanso momwe amasamalirira.
7. Ntchito zambiri
Ma MCCB ali ndi ntchito zosiyanasiyana, kuyambira ma voltage otsika mpaka ma voltage okwera. Ndi gawo lofunikira kwambiri poteteza ndi kuwongolera ma mota, ma jenereta, ma transformer ndi zida zina zofunika zamagetsi. Ma MCCB nawonso ndi mzere woyamba wodzitetezera pomanga ma system amagetsi, ma substation, mafakitale akuluakulu ndi malo opangira magetsi.
Pomaliza
Ma MCCB ndi odalirika, ogwira ntchito bwino komanso otetezeka omwe amagwira ntchito yofunika kwambiri mumagetsi. Amapereka chitetezo chofunikira pazida, mawaya ndi antchito ku zoopsa ndi kuwonongeka komwe kumachitika chifukwa cha mafunde ochulukirapo komanso mafunde afupiafupi. MCCB imakonza maulendo apamwamba, chitetezo cha maginito otenthetsera, kapangidwe kakang'ono, mawonekedwe owunikira, kulimba komanso kusinthasintha kumapangitsa kuti ikhale chisankho chabwino kwambiri pamagetsi aliwonse. Kuti muwonetsetse kuti magetsi amagwira ntchito bwino komanso motetezeka, sinthani ku ma MCCB ndikuwona zabwino zomwe amapereka.
